MECHANISM FOR PROVIDlNG ONE END 0F OF NEW YORK, N. Y.

SPECIFICATION forming part of Letters Patent No. 596,564, dated January4, 1898.

Application filed April 1 5, 1897.

each comprising a tobacco filler inclosed in a paper wrapper and havingone end of the wrapper coated or covered with moisture-resisting orfwaterproofing material to serve as a mouthpiece; and'the inventionconsists in an improvement in mechanism or devices for accomplishingthis result. Heretofore it has been customary, in order to protect theend of the cigarette from the effects of the moisture of the mouth ofthe smoker, which quickly permeates the thin paper wrapper and soaksinto the filler, thus interfering with the smoking and flavor ofthecigarette, to provide short mouthpieces made in separate pieces andslipped over theends of the cigarettes. These mouthpieces are generallymade by forming paper blanks into funnel shape and coating them withmelted paraffin or similar material, and although they are efiz'eetivefor the purposeint'ended they add materially to the expense of thecigarettes. It has also been the practice to some extent when thecigarettes are made by the individual proccssthat is,.b v Wrapping shorttobacco fillers of the length of the completedcigarettes in short paperblanks of substantiallythe same length. as the fillersto apply by anysuitable means a coating of melted pa'raffin or other moisture-resistingmaterial to one, end of the wrapper-blank and after the coating hasdried or hardened to apply such wrap- I per to the filler to form thecompleted cigarette. A cigarette made in this way will be provided witha substitute for a mouthpiece which is integral with the cigarette andwill protect to a large extent the mouth end of the cigarette frommoisture as it is smoked.

\Vhen cigarettes are made individually, as before described, it is easyto apply the de- Serial No. 632,198. (NomocleLl sired coating to one endof each wrapperblank before such blank is wrapped around the tiller andthus produce the desired result;

but when the cigarettes are made by the continuous process--that is, bywrapping and securing a long or continuous strip of-paper around a longor continuous filler or rod of tobacco and then severing the; longcigarette thus produced into short marketable lengtl1s it hasbeenconsidered impracticable, althoughvery desirable, to provide that eachsevered cigarette shall have one end of its wrapper suitably coated toprotect it from moisture. This result is especially important in view ofthe fact that a large volume of ciga-. rettfes are made by thecontinuous process and {that their wrapper endscannot-bethus coatedafter the cigarettes have been severed from the long cigarette withoutconsiderable expense. and the liability that the coating material willbe brought in contact with the filler of the cigarette.

It is the object of my invention to accomplish this resultin anefiicient and economical manner by forming a long or continuouscigarette comprising a long or continuous filler or rod of tobaccoinclosed in a longpaper wrapper and providing such cigarette with Figurel is a view of a long cigarette provided'with rings or sections ofcoating material. Fig. 2 is a section of a wrapper-strip .provided withsections of coating material.

Fig. 3 is a short or marketable cigarette having one of its endsprovided with a ring or section of coating material. Fig. 4 is a sideelevation of a machine for making cigarettes by the continuous processand a mechanism for applying coating material in sections to a longwrapper-strip and mechanism for cooling the same. Fig. 5 is an end viewof mcch tions f coated material of greaterwidth and greater distanceapart than those of Fig. 2,

and Fig. 8is a view of. a long cigarette provided with rings or sectionsof coating materialof greater-width and at greater distances apart thanthe cigarette shown in Fig. 1.

Referring to the drawings as illustratin my method, A' of Fig. 1represents a long ci arette provided with sections or rings B of coatingmaterial, which extend around the exterior of the cigarette. These ringsare formed by applying to the paper wrapper a thin layer or coating ofany suitable material which willreadily dry. or hardenand will preventthe moisture of the mouth of the smoker from penetrating through thethin paper ofthe wrapper. Melted paraffin, stearin,-or any othermaterial not injurious or disagreeable to the smoker and which can'beeasily applied and will quickly dry orharden to form a thin even coatingupon the wrapper-strip may be employed. v

. The width of the sections-orrings B when they are arranged as shown inFigs. 1 and 2 is preferablyabout one-half of an inch, and

the distance between them, including the width of one of the sections orrings, is equal to the length .of the mechantable cigarettes to beproduced. Instead of arranging or disposing the sections or rings B asshown in Figs. 1 and 2 they maybe arranged as. shown in Figs. 7aud 8,where they are about one inch in width and theirdistances apart,including the width of one of the sections, is double that of the lengthof the short or merchantable cigarettes. When the long 'cigarette isformed and provided with rings of coating material, as shown in Fig. 1,it is divided into short or marketable cigarettes by cut ting orsevering it along or near'the'line of union of the rings 13 with the,uncoated portions' of the cigarette, so that each severed cigarette willhave one end of its wrapper protected by the coating material. In casethe rings B aredisposed. as shown in Fig. 8 the long cigarette isdivided or severed along the lines as as, which pass through the rings Band also midway between the rings 13, as along the lines 1 y, asindicated in Fig. 8, thus effecting that the contiguous ends of twoshort cigarettes are provided with a coated section or ring. Thedivision of the long cigarettes into short or marketable lengths may beaccomplished by any cutting devices adapted .for this purpose.

Referring now to the drawings asillustrat- 1 ing a preferred form, ofmechanism embody ing my invention, Fig. 4 shows a machine, as X, formaking a long or continuous cigarette by wrapping and securing a longstrip. of p'aper around a long filler or rod of tobacco, and

rings of coating material with the body or uncoated portion of thecigarette, these mechani'sms being so arranged in relation to each otherthat they will operate together to pro-' duce the desired results. g

The main operative parts of the cigarette- -machine X, as shown in thedrawings, are

suitably'mounted ona frame 0, and consist of filler-forming devices D,devices E for wrapping the paper strip around the fillerrod, devices foradvancing the paper'strip and filler-rod, as belt F, devices, as G, for

securing the wrapper-strip around the fillerrod, and devices,'as H, fordividing or severing the long or continuous cigarette intoshort ormarketable lengths.

Itis not considered .necessary to describe in detail the specialconstruction and operation of the parts and devices above referred to,as they may be in all essential particulars substantially the same asthose described .in

United States Letters Patent No.- 247,795,

dated October 4, 1881, to which reference is here made, or they may beof other and different construction, provided they operate to deliver along or continuous filler or rod of tions at desired distances from eachother.

anda device for cooling such material after it has been applied andbefore the strip isv brought in contact with the filler-rod are shown inFigs. 4,5, and'6 of the drawings, in which 1 is a frame convenientlysecured to the base of frame 0 of the cigarette-machine X, in whichare-rotatively journaled rollers 2, 3, and 4, the latter being arrangedso that its periphery will rotate in a reservoir or receptacle 5, whichcontains the coating material to be applied to form the sections B uponthe wrapper-strip A. The rollers 2, 3, and 4 arepreferably driven bysuitable connection with the main shaft J of the cigarettemachine, as bybeveled gears K and 6, the latter being fixed to the upper end ofvertical shaft 7,-whoseopposite end carries gear 8,1

. of roller 2," which roller is preferably loosely Roller 3 is driven bymounted on its shaft. gear-wheel 11 on shaft 10 meshing with gearwheel'12 on shaft of roller 3, and roller 4 is driven by gear-wheel 1'2meshing with gearwheel 13 on shaft of roller 4. The length of rollers 2,3', and 4 is preferably equal to or a little greater than the width ofthe paper strip A, and the roller 3' is provided with one or more ribs14, extending along the length of its peripheral surface and parallelwith its axis, and this roller is arranged relatively'to the rollers 2and 4 so that as the roller 3 ro tates the ribs 14 will come intocontact with the surfaces of the roller 2 and 4. The reservoir 5 may beof any aterial and shape adapted to receive and hold the coatingmaterial in proper relation'to roller 4 and is preferably made"vertically adjustable by' any suitable devices, as by screw-bolts 15,extending through brackets 16 and taking against the flan es 17, formedon the side of the reservoir. A scraper or doctor 18 for the purpose ofremoving any excess of coating material from the surface of roller 4 isconveniently secured to the edge of the reservoir 5 and made adjustableto the surface of the roller by a set-screw, as 19.

The coating material-as paraflin, stearin,

or any other suitable substance adapted for the purpose indicatedmay.bemelted in the reservoir 5 or kept in the desired state of fluidity byany suitably-applied heat, as by a jet or flame of lighted gas from aburner 20, located beneath the reservoir, and the rollers 3 and 4 may beheated to maintain the coating material in a fluid or melted conditionas it is conveyed from the reservoir to the paper strip by a current orcurrents of heated air applied to-the interiors of these rollers. Aconvenient construction and arrangement for this purpose is to make therollers 3 and 4 hollow or provide them with cavities and to formchannels 21, leading through one end of their shafts and connected withthe ends of pipes 22 and 23, which lead from a Bunsen burner 24 orgotherdevice for heating the air. The rollers may be of any suitable materialas rubber, brass, or other metal which'will 1 take the melted materialfrom the reservoir 5 and properly convey and apply it to the pa-' perstrip as it is advanced between the roll ers 2 and 3. i

The arrangement of the ribs 14 on the'roller.

3 is such that they will take the coating material from the surface ofthe roller 4 and apply it to the paper strip in sections B of thedesired width and at equal distances apart, as shown in Figs. 1 and 2,the distance of the sections B from each other, including the width ofone of the sections, being equal to the length of each of the cigaretteswhen-they are severed from the long cigarette.

The devices for advancing the paper strip.

I through the mechanism which applies .the

. coating material are arranged to operate in 6o properrelation to or inunison with-the devices which' advance the strip and filler through thewrapping devices and deliver the long cigarette to the cutting-ofidevices. In the construcilion shown in the drawings the device whicperforms these functions is the. endless belt F, which passes throughthe wrapping devices and by its constant move ment drawsthe stripbetween the rollers 2 and 3 at the same rate of speed at which itadvances the strip and filler through the wrap ping devices and deliversthe completed long cigarette to the cutting-off devices. The belt F isoperated by passing over the pulley L, which is driven from the mainshaft J through the beveled gear M, meshing with beveled gear N, thelatter being fixed to the pulleyshaft. As the cutter-blade Q is arrangedto come into contact with the long cigarette and sever therefrom asingleshort cigarette at each complete rotation of the main shaft J, the gearM should be so related to the gearwheel Non the pulley-shaft that ateach rotation of the shaft J the desired length for each short cigarettewill be advanced past the cutter-bladeO, while the paper strip will perstrip as often as a cigarette is presented to the cutter to be severed.It is necessary to so adjust the cutter-blade O that it will sever thelong cigarette at or close to the line of union of the sections or ringsB with the body or uncoated part of the cigarette, the severing cutbeing preferably along the lines a: w, as seen in Fig. 1. It isdesirable that the out should be through the uncoated portion of thecigarette, but as near as practicable to the coated sections or rings,so that, on theone hand, little or none of the coating material will beon the lighting end of the cigarette and, on the other hand, only asmall section or line of the uncoated wrapper will be on the extrememouth end thereof.

To obviate the liability of the lighting ends of the cigarettes carryingany of the coating material, a different disposition or arrangement ofthe sections or rings B is easily made.

Instead of applying the sections at a distance apart substantially equalto the length of the.

desired cigarette, as shown in Fig. 2, they may be double such distanceapart, as shown in Fig;. 7, and in this case they are preferably aboutdouble in Width, so that when the long cigarette is presented to thecutter-blade to be severed it will be in the condition shown in Fig. 8and the cutter will be adjusted or set to cut along the lines we: and 'yy, as shown in Fig. 8. In this case a single cut will form the mouthends of two cigarettes,

while the next cut will form the lighting ends of two cigarettes, orvice versa. The only change required in the mechanism to accomplish thisresult is to increase the width of the ribs 14 on roller. 3 and arrangethem at front of the blast and the strip will be so held' doublecircumferential distance from each other.

To facilitate the hardening or drying of the coating material after ithas been applied to the wrapper-strip, so that it will not adhere toorsoil the b,elt F or other parts of the cigarette-machine, a blast orcurrent of air may be directed upon the strip at any convenient pointof. its advance. A mechanism foreffecting this result is designated by Zin Fig. 4 and is located to deliver a blast of air against the strip asit passes over a pulley 25, the length of the pulley being preferablyequal to or greater than the width of the strip. The coated sections 13as the strip passes over the pulley will be brought directly in inposition at this point that -theblast will be uniformly delivered acrossits entire width. The mechanism Z may be of any construction adapted tocreate and deliver the desired blast of air upon the strip. As shown inthe drawings, it consists of a rotating fan 26, mounted on shaft 27,which is driven from main shaft J of the cigarette-machine throughpulleys 28 and 29, connected by belt 30, and gears 31 and 32.

The expression long or continuous ciga-.

rette as herein used is applied to a cigarette whose length is equal toor greater than the combined lengths of several cigarettes as they aregenerally sold to consumers in the 7 market.

The operation of the mechanism hereinbefore described, and shown in thedrawings, is briefly as follows: The long paper strip A is drawn, underproper tension, from a reel or other convenient supply, and is properlythreaded through the mechanism, passing between the rollers 2 and 3,over the pulley 25,.and through the wrapping devices E,above andin'contact with the endless belt F, by

which the strip'is continuously advanced.

As the strip passes between the rollers 2 and 3 the sections B, ofcoated material, are applied at equal and desired distances apart by Xthe pressing contact of the ribs 14 of the roller 3, this pressure beingresisted by the frictionally-driven roller 2, and the ribs taking thecoating material from the surface of roller 4, which dipsintothereservoir 5. The

, applied coating material is dried or cooled during the passage of thestrip from the rollers 2 and 3 to the point of its contact with theendless belt F, and this drying or cooling may be hastened, if desired,by the impact of a blast of air upon the strip as it passes in itscourse. When the strip reaches the wrapping devices, the filler-rod,formed by any suitable mechanism, is delivered upon the strip, which iswrapped around the rod, as the two are advanced through the wrap pingdevices, the wrapper being secured in place by the devices G, thusforming a long or continuous cigarette provided with a series ofsections or rings B of coating material extending around its exterior,as shown in Figs. 1 and 8. The long cigarette is then advanced to thecutting-off blade 0, which is set or arranged to operate in unison withthe mechanism which applies the coating material to the strip to severthe long cigarette into short. or marketable lengths in the mannerbefore described, so that each severed cigarette will carry upon one ofits ends a section or ring of coated material to serve as a mouthpiece.

In the construction of the mechanismshown in the drawings the operationsarepreferably continuous, the strip A being continuously advanced andsupplied with sections of coating material, the filler-rod beingcontinuousl y delivered upon the strip,and the strip being continuouslyand progressively wrapped around the filler-rod to form a long orcontinuous cigarette, the continuity of the operations being limitedonly by the length of the cigarette or filler-rod or the action of themachine.

It is not intended to limit this invention to any special form orconstruction of devices or mechanisms for applying the coating materialor for forming and delivering the fillerrod to the wrapper-strip, orwrapping and securing the same around the rod, or for dividing the longcigarette thus formed into .short or marketable lengths, sincerit isevident that many forms of mechanisms or devices may be employed forthese purposes without departing from the principle of the invention.

That is claimed as new is- 1. The combination substantially as setforth, in a mechanism for making cigarettes withmoisture-protected ends,of devices for applying a series ofsections of coating material to along wrapper-strip, devices for delivering a long filler or rod oftobacco to the strip, devices for wrapping and securing the strip aroundthe filler-rod to form a long cigarette with a series of surroundingrings of coating material, and devices for severing the long cigaretteinto short marketable cigarettes, whereby each severed cigaretteisprovided with a ring of coating material at one of its ends.
